Having just gone through a troublesome warranty replacement (due to spoiler cracking) of my 2015 C4 Picasso Exc+ motorised rear tailgate, I might just be being paranoid.
But, about 5 seconds after I start the engine there is a short motor running sound (about a second long) that I can hear inside the car- coming from somewhere at the rear of the vehicle. It's a similar sound to a central locking motor.
In the 18 months I have owned the car, I can't say I have noticed it before.
I thought it might be related to the tailgate lock? Does anyone know if it locks itself when you start the engine for security maybe? I don't think it's the diesel pump because it only seems to happen once. Has anyone else noticed this or have an idea what it might be?

Problem solved.
It appears that when the 'bodyshop' replaced the tailgate- they did not initialise it properly. After much research I found that to do this, you need to open it fully using the exterior button, then close the tailgate manually by pulling it slowly closed.
After I did this, the motor noise had gone and the safety feature where it stops on meeting an obstacle, works correctly on the opening and closing. I noticed it only did it on opening before.
Hope this information might be of use to someone.
